You'd be surprised at how many games won't run maxed at 1440p with a single 980. The difference between 1080p and 1440p may not seem like much, but it's pushing nearly twice as many pixels. On my box it runs around 80-100fps in single GPU mode which for a brand new AAA title is actually really impressive.
One thing I did notice, though. Many people complained about GTA4 being terribly optimized on PC. It was demanding, but one of the reasons it was so demanding is that it came with about a dozen sliders that you could push WAY past what the console version did in terms of view distance/detail/whatever. People would push every slider to the max and then complain that the game doesn't run at "max" settings very well.
In GTA5, they have the standard settings and then another section of advanced settings that are turned off by default. That whole section comes with a performance hit warning label.
That traffic slider....at max, time square had like 150 cars in it, absolutely ruined the framerate.
Yeah, people get obsessed with "max settings" without stopping to realize that this doesn't always mean the same thing in every game. If a game -lets- you crank it higher than any modern system can do, then it gets criticized for being poorly optimized. Sometimes that's true (like in Dead Rising 3 where literally no computer today can run it under even decent settings at 1440p) but GTA 4 got an unfair rap.
Some games, like Crysis, had settings nobody at the time could run. The difference is that those settings made the game look amazing and far better than any game before.
GTA4 maxed out never looked impressive - hence people calling it badly optimised.
Not only that, but the game ran poorly, regardless of settings.
There is this one issue I hated about the game when I played it on it's initial release that still exists. The characters changing their own clothes. I get why they did this, but there needs to, at the very least, be a way to set up your own handful of outfits or something. Trevor can still wake up in his underwear or in a dress though because that's amusing. But I don't really enjoy going on my crime spree in khaki shorts and loafers...
Worse than that is when you need/want to do something on Trevor and he's in the middle of a bloody police pursuit!
